ARCHITECTURAL DESIGN

DSP Pipeline Core

Sonaura routes multi-channel audio through a sequential-parallel pipeline in real-time.

Audio Processing Chain

Every audio sample captured from your browser tab passes through this exact signal chain inside the offscreen thread.

Sonaura Audio Processing Pipeline

HRTF 5.1 Surround Matrix

Splits standard stereo audio into 6 channels (Front L/R, Center, Surround L/R, and Subwoofer LFE). High-frequency rear attenuation and Haas delays (22ms left, 28ms right) place speakers dynamically in a virtual 3D theater space.

Surround Layout

10-Band EQ & Auto-Curves

Parametric equalizer spanning 31 Hz to 16 kHz. Bass boost and treble enhance controls adjust shelves and peaking bands with cascading attenuation to target ideal cinema responses.

EQ Curves Response

Dialogue Clarity

Extracts dialogue center frequencies, filtering out low end (< 120Hz) and adding a presence boost (+2.5dB at 2kHz) so voices are never drowned out by background mixing.

Subharmonic Exciter

Generates tube-like warmth for sub-bass by running the low-end signal through an asymmetric waveshaper, introducing rich even and odd harmonics without digital clipping.

Cinema Hall Reverb

Simulates a mid-sized movie theater. Uses synthetic convolution reverb with 0.55s decay, cross-talk Haas reflections (2.5ms), and highpass/lowpass filters to prevent muddy tails.

Privacy Policy

Last Updated: July 2026

Sonaura 2.0 ("the Extension") is committed to protecting your privacy. This Privacy Policy explains our data collection and usage practices.

1. No Data Collection or Transmission

Sonaura 2.0 does not collect, store, or transmit any personal data, audio recordings, browsing history, or system information.

  • Audio Processing: All audio capture and digital signal processing (DSP) occur entirely locally and in real-time within your browser's execution memory. No audio stream is ever recorded, written to disk, or sent to any remote server.
  • Local Storage: Custom preset profiles are stored exclusively on your local machine using the browser's local storage API (chrome.storage.local). They are never synchronized with external servers or shared with third parties.

2. Browser Permissions Requested

To perform its core functions, the Extension requests the following permissions:

  • tabCapture: Necessary to capture the audio stream of the active tab in order to apply the digital signal processing chain (surround virtualization, reverb, and equalizer).
  • offscreen: Used to create a helper offscreen page to run the Web Audio API context (required by Manifest V3).
  • storage: Used to persist your custom equalizer and mixer presets locally.
  • activeTab: Used to access and process audio on the specific tab you select when enabling the extension.

3. Changes to This Policy

We may update this Privacy Policy from time to time. Any changes will be posted directly within the repository.

4. Contact

If you have any questions or feedback regarding this policy, please open an issue in the project's official repository.
